[The prognostic value of evaluation of minimal residual disease using technique of flow cytofluorometry during application of therapy of chronic lymphatic leukemia].

The achievement of molecular remission is associated with increasing of survival of patients with chronic lymphatic leukemia. The important direction of research is seeking of parameters applicable to forecast of response to therapy. The purpose of the study was evaluating prognostic significance of indicator of minimal residual disease detected by technique of flow cytofluorometry of peripheral blood of patients with chronic lymphatic leukemia during therapy application.

[The characteristics of evaluation of expression of ZAP-70 in tumor cells under b-cell chronic lymphatic leukemia using the flow cytofluorometry technique].

The b-cell chronic lymphatic leukemia is the most common among all lymphatic proliferative diseases and is characterized by significant variability of its clinical course. The mutation status of genes of variable region of heavy chains of immunoglobulins (IgVH) is the most reliable prognostic factor forecasting time until beginning of treatment in case of b-cell chronic lymphatic leukemia. However its detection nowadays is inaccessible for routine diagnostics.

[The detection of minimal residual disease in patients with chronic B-cell lymphatic leukemia using patient-specified polymerase chain reaction].

The new effective protocols of treatment of chronic B-cell lymphatic leukemia, including purine analogs and monoclonal antibodies, provide robust remissions under this disease. Accordingly, the requirements to remission quality assessment are changed too. In particular the assessment of minimal residual disease is obligatory.
